i siMoKE-CONDENSER.

SPECIFICATION forming part of Letters Patent N0. 774,849, dated November15, 1904.

Application filed May Z8, 1902.

To nfl/f 1071/0711, it may concern:

Be it known that I, HENRY MATTHEWS, a citizen of the United States ofAmerica, residing at lhfasliington, in the District of Columbia, haveinvented certain new and useful Improvements in Smoke-Condensers, ofwhich the following is a specification.

This invention relates to smoke-condensers, and more particularly to,that class which are adapted to inject a jet of steam into the stack.

The object of my invention is to provide a smoke-condenser soconstructed as to inject several jets of steam into the stack at one andthe same time, thereby causing' a complete mingling of the steam andsmoke and reducing the condensationY to a minimum. A

Another object of my invention is to provide a smoke-condenser which isexceedingly cheap and simple, one which may be easily and quicklyapplied and will efciently perform all of its intended functions.

With these objects in view and such others as may hereinafter appear myinventionconsists in the particular construction of the various partsand in the novel manner of combination and arrangements of said parts,all of which will be fully described, and specifically pointed out inthe claims.

In the drawings forming a part of this specification, Figure l is asectional view of a furnace, illustrating my invention as applied. Fig.2 is a detail view of the nozzle or jets. Fig. 3 is a side elevation ofthe nozzle or jet.

Referring by letters to the drawings, A represents the furnace, B theboiler, and C the door opening into the usual iiue D, which leads to thestack E. Detachably connected to the steam-pipe F, which communicateswith the boiler B, is a pipe G, which passes through an aperture H inthe Vdoor C, the said aperture and steam-pipe F serving to support apipe G, which is provided with a stop-cockI, adapted to control'the flowof steam. The pipe Cr projects a short distance into the iiue and isprovided with my improved jet, con- Serial No. 109,350. (No model.)

sisting of a disk J, secured to the pipe G by Ythe usualA threads. Thisdisk is provided with channels K, leading from the periphery thereof tothe aperture which receives the pipe G. Mounted in each channel upon theperiphery of the disk are angular pipes L, terminating in jets M,adapted to throw or inject the steam `in a circle.

Mode of application:l When it is desired to feed the furnace, thestop-cock I is opened, thereby allowing the steam to pass through thepipeG, entering the injector, from which it passes through the jets Minto the flue D. The fuel is then fed to the furnace and is caused toignite instantly, owing to the increased draft. However, those productsof combustion which are unconsumed are so completely mingled with thejets of steam that condensation is reduced to a minimum. After thefurnace has been fed and the doors closed the steam is shutoff and theapparatus is not employed again until it is desired to slice or refeedthe furnace.v

I deem the foregoing explanation suficient that the invention will bereadily understood by all conversant in such matters, the eX- tremesimplicity-rendering an elaborate description unnecessary.

Having thus described the various features of my invention, what I claimas new, and desire to secure by Letters Patent, is

In a smoke-condenser, a steam-pipe projecting through and supported bythe flue-door, the free end of the pipe terminating in the center andnear the mouth of the flue, a nozzle upon the free end of the pipe, thesaid nozzle consisting of a disk having channels leading from itsperiphery to the steam-pipe, angular pipesections secured in eachchannel, each section terminating in a jet, and a stopcock uponV thesteam-pipe, substantially as specified.

HENRY MATTHEWS.
